Beit known that I, PRESTON DAvinaiesiding at No. 12 Kempson Road, Walham Green, Fulham,London, in the county otZMiddleseX,

" England, have invented certain new-andus'eful Improvements in Ball-Bearings, (for which have-received Letters Patent in Great Britam, No.17,407, dated September 29, 1892, and

. iuGerm'an-y, No. 69,613, dated November 22,-

1892,) of which the following is a specification.

My, invention. relates to ball bearings adapted especially for use in other wheels, inwhich bearingsareprovided at any desired number of intermediatepoints, all capable of adjustment approximately to the same degree-by one mechanical action,

the load on the bearing being equally distributed over the axle.

The accompanying drawings illustrate my invention applied to a'bearing suitable for a bicycle.

,Figure 1 is a longitudinal section of the bearing; line m-,-a: vation.

The'a'xle a upon which the bearingrevolves I preferto make of mild steel, andthe. ball paths a a a ofh'ardened steel, securelyattacked-to the axle, but capable of adj ustment laterally in any convenient'man ner. Atthe ends of the axleI'provide collars 17b, having annular grooyesfor the balls-c. The collar b, is made ,fast to at on the axle, but thecollar-b Fig. 2,-a-cross section thereof on the bailsby means of the screw on th e axle, as

shown, and is secured or locked in position is placed between y the nut d. Awasher d the collar b,-and the nut'd;and is prevented from revolving by itsengagemeut with-a flattenedportion of theaxle.

Contiguous-to the collarsb b are flat'plates" e e, one screwed into-each end of the hollow tubeo hub. in afixed need only be moved when it'is'de ired foalter'the' position of thebearing-in its case,hut V the plate'e isicapab le ofadjjiist-ment forwear of the hearing by means of'a key havingipro jections which engage with openings e* v'elocipede and.

face of the plate. This plate is secured in any desiredposition by a set screw-e which can, in turn, be secured. oythe lock nut a The hub or'casing f, which'forms the outer part of the bearing, is shown in the drawings shape orformfor the purpose for which it-is vintended to be used. v I

l I place in the casing single end cones, andany desired number of double cones g, each vformed with beveled edges, as shown, so that in tightening the bearing-in themanner hereinafterldescribed, any loose'ness profd'ucedby radial wear is overcome. These cones which form bearings for the halls h are capable of position and wear by the plates e and a. They are caused to revolve (in the case of the bearing "being used 7 for a wheel) withtheouter'casing fiby means of a'fe'ather or key f ,which is secured to the casing f by screws f brought to bear equally 'upon all the balls h, the beveled edges of'such cones servingto force the balls onto their axial pathsfovercoming allfradial wear, vand distributingtlie load equally along the bearing. Any usual or suitable means may be provided for the lubrication of the. hearing. The number of cones and bearinglsurfaces may be. varied in accordance with thesizes of the total bearing, and'the load intended to be put upon it. I e I v I As will be observed,'the adjacent ends of each other,

and may therefore be adjusted toward each jother to take up wear, resulting from the com witheach omen-balls arranged between the adjacent inelined endsof the cones,- end in the as plane on its exterior, but it will be understood that such casing can be ofany desired Upon turning the plate- 9"s i ng adjacent inclined ends out of contact pieces or disks adj ustably connected with the i In testimony whereof I have hereunto subsleeve or casing,a. collar 1) secui'ed to the axle scribed my name. and having recesses containing balls bearing on one of the end pieces, a collar I) having recesses containing balls bearing on the oppo- Witnesses:
